InterDigital over the past eight years," said William J. Merritt,
President and Chief Executive Officer of InterDigital. "During his
tenure as Chief Financial Officer, Rich has provided strong leadership
and built a very solid finance organization. He has always been
squarely focused on creating and returning value to shareholders, a
legacy that will continue to be a cornerstone of InterDigital. I am
also thankful for Rich agreeing to continue with the company while we
search for his successor. I expect that the financial discipline and
